I'm doing a bit of work on my 914 and want to take care of the leaking push
rod tubes.  I have new o-rings and have read that I can use RTV silicone to
help the o-rings seal.  My question is: Do I simply have to remove the rocker
arms, slide the push rods back far enough to get the old o-rings off, clean
up the ends of the tubes, RTV the o-rings and reassemble everything?

I have the car elevated enough to be able to work from the under side and it
looks like there is not enough room to slide the tubes completely out of the
heads but enough room to replace the o-rings.

Thanks,
Roger
